I have a website with over 300 posts and initially I used to use external image URLs in my blogs instead of uploading it to my DB and using them.
Is there any way to automatically get all the external image urls on all 300+ posts, to be uploaded onto my website and use the uploaded media's urls instead of the external image urls?
To be clearer, for example, if I am using a Lion's image from wikipedia, with wikipedia's URL..... I want to automatically upload that image onto my website and use the uploaded lion image url instead of the wikipedia url.
